Suspended sediment load in the Amazon basin: An overview

In this report the state of knowledge of sediment transport by rivers of the Amazon drainage basin is reviewed. On an annual basis the Amazon river transports about 1200×106 tons of sediment from the South American continent to the ocean, which puts it among the world's largest rivers in this respec...
